Mune masisitimu ekufambisa kwemvura, mahosi anoshanda sebhiriji rakakosha pakati pemidziyo uye midhiya, uye kuita kwavo kunokanganisa zvakananga kugadzikana uye kuchengetedzwa kwehurongwa PTFE hose uye PVC hose, semhando mbiri dzakajairika dzemahosi emidziyo, imwe neimwe ine yakasarudzika mabhenefiti uye maapplication. Kunzwisisa kusiyana kwavo kunogona kutibatsira kuita zvisarudzo zvine musoro zvichibva pane zvatinoda chaizvo.
- Kuumbwa kwemakemikari uye kugadzikana
Iyo PTFE hose yakagadzirwa ne polytetrafluoroethylene material, ine yakanyanya kugadzikana kemikari uye inenge isingabatwe nechero zvinhu. Inogona kuramba kurwiswa kwezvinosvibisa media senge acids, alkalis, uye munyu. Yayo molecular chimiro haina kabhoni-kabhoni kaviri mabhondi saka ine yakakwira oxidation kuramba. Kusiyana neizvi, hose yePVC isimbi yekugadzira polymerized kubva kuvinyl chloride monomers. Kunyangwe iinewo yakanaka corrosion resistance yayo kugadzikana kwemakemikari uye oxidation kuramba yakadzikira. Musiyano uyu unoita kuti hose yePTFE iwande zvakanyanya munzvimbo dzinotyisa.
- Maitiro ekuita
PTFE hoses inoita zvakaenzana zvakanaka maererano nekuita. Madziro avo emukati anotsvedzerera ane yakaderera friction coefficient, iyo inogona kunyatso kudzikisa kupikisa panguva yekusagadzikana uye kuderedza kupfeka kwemidziyo. Pamusoro pezvo, PTFE hoses ine yakanakisa yakakwirira uye yakaderera-yekushisa kuramba, ichivabvumira kushanda zvakadzikama muhupamhi hwetembiricha renji -250 ℃ kusvika 260 ℃ vasingaite brittle kana kuchembera. Kune rimwe divi, maPVC hoses, nepo aine kumwe kuchinjika uye kusimba, anowanzo chinja pakupisa kwakanyanya, achidzikamisa kushandiswa kwawo munzvimbo dzekupisa kwepamusoro.
PTFE hoses, nekuda kwekugadzikana kwayo kwemakemikari, kupikisa kwekushisa kwepamusoro, uye kusagadzikana kwekusapfeka, inoshandiswa zvakanyanya mumaindasitiri akadai semakemikari,, gasi rechisikigo, chikafu, uye mishonga uko kunodiwa zvinhu zvepiping zvepamusoro. Vanonyanya kukodzera kubata corrosive media uye high-pressure environments. Kune rumwe rutivi, mapaipi ePVC, ane mutengo wakaderera uye maitiro akanaka ekugadzirisa, anoshandiswa zvakanyanya mukuvaka dhiraivha, kufefetedza, masisitimu ekupa mvura, pamwe nemukati nemagetsi minda uko kuchinjika kuisirwa uye kudzora mutengo kunodiwa. Pane misiyano yakakura mumidziyo yezvinhu uye minda yekushandisa pakati pezviviri izvi.
Mukupedzisa, isu tinosimbisa zvakare kusarudzika uye kuwirirana kwezvinhu zviviri izvi hose. PTFE hoses, ine yakanakisa makemikari kugadzikana yakaderera friction coefficient, uye kushorwa kune yakakwirira uye yakaderera tembiricha, yakave iyo inofarirwa zvinhu zvepamusoro-yekupedzisira kugadzira uye zvakanyanya kushanda mamiriro. Kune rumwe rutivi, PVC, ine mari-inoshanda uye nyore kwekugadzirisa, vakawana nzvimbo yavo mune zvakasiyana-siyana zvemaindasitiri. Sarudzo yeipi hose yekushandisa kwete chete zvinonetsa-kushanda asiwo kuita kwese uye kuchengetedzeka kwehurongwa.
